BF type seal
BF type seal
Art. BF
The BF design features a seal housing made from a forged blind flange. The welded joint between the diaphragm and the seal housing is the wetted part, so the diaphragm materials are generally the same as the flange material. The BF is typically used in conjunction with differential pressure sensors for applications such as level, flow, and absolute pressure measurement.
The diaphragm is TIG-welded to the flange and designed to provide the best performance for a specific size. This means its flexibility and shape are carefully tested and measured. The standard membrane foil thickness is 0.075 mm.
